Answer:
Torque will be equal to 4.176 N-m
Explanation:
It is given moment of inertia about knee joint 
Angular acceleration produced 
We e have to find the torque
Torque is equal to
, here I is moment of inertia and
is angular acceleration.
Torque will be equal to 
So torque is equal to 4.176 N-m
(9.39 x 10⁹ sec) x (1 day / 8.64 x 10⁴ sec)
= (9.39 / 8.64) x 10⁵ days
= 108,680.56 days
Answer:
1. It may change the direction of an object in motion.
2. It may cause change in velocity of an object in motion.
Explanation:
1.It may change the direction of an object in motion.
When an object is in motion,an applied force on that object may change its direction.
For example, a sailboat moving eastward, can suddenly change its direction by interaction of a storm wind blowing form the south.
2. It may cause change in velocity of an object in motion .
A force applied to an object in motion can increase or decrease its speed. When the force is applied to the object in motion in the direction of that object, its velocity may increase.
On the other hand, when the force is applied in the opposite direction to the object in motion, its velocity may reduce.
That it will erupt upon contact. Hope it helps!
